An a cappella supergroup? Sounds paradoxical, absurd, perhaps even dangerous; but The Groovebarbers is all these things...and more. Hand-ladled from the cream of the a cappella crop, each member of this all-vocal powerhouse quartet is a bona fide star in his own right. Sean Altman, Charlie Evett and Steve Keyes are all former members of the pioneering contemporary a cappella group Rockapella. With the addition of renowned vocal guru Kevin Weist, The Groovebarbers have immediately established themselves as the 'go to' vocal group for rock, doo-wop, jazz and even (no way!) barbershop!
